STOP FOR DOUBLE GATES.

SPECIFICATION forming part of Letters Patent No. 367,926, dated August 9, 1887. Application filed June 27, 1837. Serial No. marsh- (No model.) Patented in England April 20, 1887, No. 5,110.

To all whom it may concern.-

Be it known that I, MILEs POSTLETHWAITE, Esquire, a subject of the Queen of Great Britain and Ireland, residing at The Hollins, Whitehaven, in the county of Cumberland, England,

ject' to provide simple and efficient means whereby the said stops are automatically raised when the gate or'the likeis closed and lowered when the gate is opened, so as to constitute 11o obstruction in the roadway past the gate.

According to my invention I employa stop capable of turning upon a center, so that when the gate is opened the said stop falls by gravity from a vertical to a horizontal position, andis received in a recess or casing situated at the part of the roadway whereat the portions of the gate meet when the gate is closed. Beneath the said stop is a leverattached to a shaft or rod situated in a casingbeneath the groundlevel and extending in a line parallel with the gate when closed. On the other end of the said shaft or red is another lever or arm,which projects above the roadway near to the hinge of the gate, so that as the gate is being closed it comes into contact with this arm and partly rotates the rod or shaft, whereby the lever at its opposite end bears on the stop so as to raise it into position for the gate to come into contact with it. When the gate is opened, the stop falls, as described, and in so doing the rod or shaft is acted upon thereby, so as to bring its levers into position for again being acted upon to raise the stop when the gate is closed. There may be one stop for both the sides of the gate, the said stop extending across the place where the parts of the gate meet when closed on either sideasuficient distance for both parts of the gate to come into contact therewith, or the said stop may be arranged in such a position that only the part of the gate which is first closed comes in contact with gates open.

it; but I prefer to have twostops, one foreach part of the gate,and an arrangement,such as I have described, for raising it,.so that whichever of the parts of the gate is closed, whether purposely or by accident, (by the wind, for instance,) a stop rises to prevent its being swung beyond its proper closed position. I will describe an arrangement according to this last plan,with reference to the accompanying drawings, from which its general application will be well understood.

Figure 1 is a front elevation with the gates closed. Fig. 2 is a front elevation with the Fig. 3 is a plan thereof. Fig. 4 is a longitudinal section; Fig. 5, a transverse section on the line 1 2, Fig. 4. Fig. 6 is a transverse section on theline3 4, Fig. 4, showing the position of the parts when the gate is closed and Figs. 7, 8, and 9 are corresponding views, showing the position of the parts when the gate is open. Figs. 4 to 9 are drawn to a larger scale than that to which the other figures are drawn, and show the arrangement for one side of the gate only, the other side being arranged in a similar manner.

In the roadway, parallel with the gates when closed,are casings A,with covers A", level with the roadway. In each of the end parts, A of the casings are stops B, turning upon a center at b, and having parts at B" at right angles, so that when the stops B are raised the parts B fill the openings in the casings in which the stops B lie when the gate is open. In each of the casings A is mounted a rod or shaft, 0, capable of partial rotation, and having fixed thereto at each end a lever or arm. That at D acts upon the stop B to raise it,while that at E is acted upon by the part of the gate at the hinge end to partially rotate the rod or shaft,

and so raise the lever D and stop B. The arm E is preferably provided with an anti-friction roller, 0, and the gates, if of wood, may have metal plates fixed thereto to bear on the rollers e and against the stops B. Vhen either flap of the gate is closed, its hinge end bears on the arm E, and by partly rotating the shaft 0 raises the lever D, which in turn elevates the stop B sufficiently for the gate to' come into ing on the stop, completely raise it to its vercontact with it. Q The gate will then, by beartical position. The bolt or bolts for fastening the gates may enter a hole at a, made in the casing for its reception. The covers A form a convenient means for keeping the pins and shafts in place endwise by hearing on the ends of the pins 1) and upon the arms E. The two parts A ofthe casings may be connected together by means of bolts passing through lugs formed thereon. The covers A" and stops B arecapable of being readily removed for the purpose of cleaning out any dust or dirt that may accumulate in the casings A.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is-- The combination, with the swinging or hinged gate, of the hinged flap or stop-piece therefor, and the shaft 0, provided with a le ver or arm acted 011 by the gate when being closed to cause a partial rotation of the arm, and also with a second lever or arm, which, when the shaft is thus rotated, acts to lift the said flap or stop-piece into StOpping position, as and for the purposes hereinbefore set forth. I11 testimony whereof I have signed myname to this specification in the presence of two Subscribing witnesses.
